i use rubberguard a lot, (and i'm a 200+ pounder too, so it's rare in my division), but lately i've been using sean williams guard more often. bring up the meathook, (i use my left leg almost always), and reach around it under the knee, trapping their arm and allowing you lots of free space to move your hips out. there's a great choke from there too, almost like a triangle but using your forearm for the pressure.
